2.1 BAR FEEDER GENERAL DESCRIPTION
The BOSS automatic bar feeder is used in the machine-tool industry and in particular, for
automatic lathe feeding. It is particularly suitable for feeding fixed or sliding headstock lathes,
numerical control or cam lathes.
The operating cycle is controlled by a PLC, integrated in the electrical control panel, which is
able to communicate with the lathe control system.
The digital operator panel makes programming easier and allows the bar feeder functions to be
controlled without leaving the lathe.
The bar feeder can be used to feed bars, pipes, various sections and metallic as well as
polymeric materials. Do not use flammable materials.
The guide channel is completely closed during machining; a pump is provided to maintain a
continuous oil flow inside the guide channel, creating a hydrodynamic support effect; these
features allow the bar to rotate at high r.p.m., with no vibrations and no surface damaging.
Thanks to the use of a "BRUSHLESS" and electronically controlled motor, the bar speed, torque
value and bar feeding position may be determined at any time during the working cycle.
The bar pusher returns with the remnant, which is removed and then falls into the remnant
recovery box through a slot of the following size: L=400 mm, for Standard Remnant Drop (CSS)
or L=700 mm for Oversize Remnant Drop (CSM). Please refer to the "VERSION DESCRIPTION"
section in ch. 2 for technical specifications.
The bar remnant ejection can be performed by the bar pusher feeding or next bar feeding.
The BOSS bar feeders are available in the following models:
BOSS 552 IC (standard version, magazine length: 21, 32, 37, 44)
When not otherwise specified, the texts, tables and pictures of this manual refer to the
standard version with the lathe on the operator's right.
